Waters 486 HPLC Detector Waters HPLC detector Waters 2487 newer version of Waters 486 HPLC older version
ships refurbished and warranted for 100 DAYS!
Wavelength range and sensitivity
The Waters 486 tunable absorbance detector provides a usable light intensity over the wavelength range 190 to 600 nanometers (nm), although its primary use is in the ultraviolet range between 190 and 380 nm. The maximum sensitivity of the instrument is 0.001 absorbance units full scale (AUFS).
Features
The Waters 486 tunable absorbance detector offers the following features:
Easy to use operator interface
Self-calibration to ensure wavelength accuracy
Battery backup to retain parameter settings when the detector is powered down or during power interruptions
A deuterium arc lamp
The patented Taper-Cell flow cell design, which reduces interference caused by refractive index effects.
Optional cells:
Non-metallic
Semi-prep
Microbore
High-pressure (optimized for operation in LC/MS) Lamp shut-off to lengthen usable lamp life
User-selectable chart mark on IV integrator output (standard on 10 mV)
Wavelength scanning to determine optimal wavelength
Diagnostic routines to verify proper functioning
A modular design for easy servicing
